SPECIFICATION forming part of Letters Patent No. 72 .2 7, a ed M y 1903- Applioationfiled November 16, 1901. Serial No- 82678. (No model.)

To all whom it may concern:

Be it known that I, ANDREW CHARLES JOSEPH CHARLIER, consulting chemist and engineer, of Sussex House, Hill street, inthef city of Glasgow, Scotland, have invented certain new and useful Improvements in Apparatus for Drawing Gaseous Liquids, of which the following is a specification.

My invention has for its object to provide 10 an apparatus by which liquids under any pressure and fully saturated with any gas can be delivered into open vessels without using the .pressure which these liquids may contain as a power for forcing the liquid into open vessels, and thus losing a very large percentage of the aeration or gases contained in the liquid.

My invention applies more particularly to aerated waters-such as soda or potash water,

lemonade, ginger-beer, kola, and syrups which after having been fully aerated can be delivered into glasses ready for consump-, tion and containing a far larger percentage of gas than can be obtained from the ordinary bottles or siphons. It is also applica+ ble to beer, stout, or other alcoholic liquids,-

as Well as being suitable for dealing with all classes of liquids, including milk, under pressure in combination with chemical gases and by which they can be delivered into open vessels at only a slightlyreduced pressure from that contained in the original cylinder.

I am aware that; apparatus has been in:- vented to deliver aerated waters under pressure into open glasses;-but such apparatusis of such a delicate nature that only liquids which flow freely likewa'ter can be dealt with; but by my present improvements '1 can deal with any liquids even as thick as syrup.

In order that my invention may be properly understood and readily carried into effect, I have hereunto appended two sheets of drawings, of which Figure 1 is a perspective View showing my 5 improvements complete, the apparatus-in this case being fixed 'to a slab. Fig. 2 isa section of the glass receptacle or vessel and cook, the former being shown cone-shaped. Fig. 3 is an elevation of the same, the vessel in this case being in the form of a cylinder. Fig. 4 shows the position of cock when open for admission of liquid, Fig. 5 for discharge of air, and Fig. 6 fordischarge of liquid from receptacle or vessel into drinking-glass. Fig. 7is a view ofupper side of a'r'nodified form of a 5 5 vessel, showing the puppet-valve. Fig. 8 is a section view of the casting K showing the manner in which the air escapes.

In carrying out my invention I provide a cylindrical, cone, or other suitable shaped receptacle or vessel A, of glass or other suitable material, which isfitted into a framework made up of a top and bottom plate B and C, which are connected together by means of rods D, one of these rods D being hollow, whereby it will serve as a passage for the escape of air from the air-chamber E at the top of the receptacle or vessel A, as will be hereinafter more fully described, or a separate pipe may be employed for the escape of the air. A fixed baiiie-plate M is providedat the upper end of the vessel Awithin the air-chamber E a distance above and across the opening which forms a communication to the vessel to prevent any liquid getting into the air-passage. V

Connected to or forming part of the bottom there is a pipe F, having a branch F with inlet-opening G'for supplying the vessel with the liquid-from the tank H. At the bottom of the pipe F there" is a'discharge-opening I for allowing the liquid to pass from the vessel A into thedrinki'ng-glass J; The branch .F isconnected to the supply-tank H by means of the'pipes'K, which pass through an icechamber S, as shown in Fig. 1. a The barrel crane or cock L is so constructed that by a quarter-turn of the lever L or tap which is connected to it it performs the various functions to be hereinafter described.

The 'modus operandi is as fOllOWSZ'WhQII it is desired to use the apparatus, thelever L is turned into'the position shown in Fig. 4, when the inlet-port N is opened, which enables the liquid to pass from the pipes K, leading from the supply-tank H partially through the port N, through port N, and into the vessel A. The lever L is further moved into the position shown in Fig. 5 and in dotted lines, Fig. 3, when the inlet-port N is closed and the air-escape T is opened, which allows the air above the liquid to pass by the baffle-plate M and down the passage in the hollow rod D or other air-escape tube along the hollow passage 0, extending through the flange of the bottom plate C and the wall of the tube F to escape through the passage T in the cock and into the passage T in the branch F, from whence the air passes through a duct in the casting K similar to the duct T, and escapes into the atmosphere at a point below the slab. The quarter-turn of the lever L is then completed, as shown in Fig.6 and the dotted lines, Fig. 1, when the port N registers with the discharge-opening I, for the liquid and the contents of the vessel A are allowed to pass freely out into the glass J. The same operation goes on continuously so long as it is desired to withdraw liquids.

The supply-tank H is provided with a backpressure valve P, an air and liquid pump Q,

so that should there not be sufficient air in the liquid in the tank H to raise the same through the connections into the vessel A this can be overcome by simply pumping the necessary quantity of air into the vessel. I

also provide an inlet-supply pipe WV, so that the tank H can be charged with liquid by means of the pump Q without having, occasion to remove the top connection K, and thereby preventing the loss of any of the gases in the tank,which is one of the disadvantages of the existing arrangement of filling tanks. Where milk is used, four hundred or five hundred pounds (or thereabout) air-pressure could be forced into the tank, whereby any germs which might be in the milk would be destroyed and the milk drawn ofl by the means already described for dealing with the other gaseous liquids, the excessive pressure of air in the tank being in this case preferably drawn off by means of the puppet-valve R. (Shown in Fig. f the drawings.) In some kinds of liquids-such, for instance, as syrupsit might be necessary to regulate or vary the pressure of air above it, and in such case I also provide a puppet-valve R, which is loaded to go off at any required pressure, as shown in Fig. 7.

The apparatus can be made in any size, so that it can be adjusted to siphons containing onlyaquart or to vessels containing any quantity of liquid, and it can also be arranged to supply any liquid, if necessary, without the use of measures so long as the glass receptacle or vessel A is duly marked to register its contents.

I claim- 1. In an apparatus for drawing gaseous or other liquids, the combination with a pressure-relief chamber, of a pressure-escape passage, an air-chamber having continuous communication with the relief-chamber and the pressure-escape passage and located between said passage and reliefchamber, and means within said air-chamber excluding liquid from said passage.

2. In an apparatus for drawing gaseous or other liquids, the combination with a pressure-relief chamber, of a pressure-escape passage, an air-chamber having continuous communication with the relief-chamber and the pressure-escape passage and located between said passage and relief-chamber, and a fixed baffle-plate within said air-chamber.

3. In an apparatus for drawing gaseous or other liquids, the combination with a pressure-relief chamber, a liquid-supply tank, an ice-chamber located between said relief-chamher and tank, suitable connection between said tank and ice-chamber and between the latter and the relief-chamber, of a pressureescape passage, an air-chamber having continuous communication with the relief-chamber and the pressure-escape passage and located between said passage and said reliefchamber, and a fixed baffle-plate in said airchamber.

4. In an apparatus for drawing gaseous or other liquids, the combination with a top plate and a bottom plate, of a receptacle positioned between said plates, supporting-rods connecting said plates, one of said rods being hollow, of a pressure-escape passage in said top plate and having communication with said receptacle, and the interior of said hollow rod at the upper end of said rod, of a baffle-plate at the entrance to said escape-passage, a suitable source of supply to said reliefchamber, a cock controlling said source of supply, and a suitable escape-passage leading from the lower end of said hollow rod and controlled by said cock.

In testimony whereof I atfix my signature in the presence of two witnesses.
